Other Parts Discussed in Thread: TPS65165
I have an application for TPS65165 , but I need to be able to control the brightness with PWM. Do yo know if TI has any recommendation to use a PWM on this part to control the brightness of LCD? Are there other…
Part Number: TPS65185 Other Parts Discussed in Thread: TPS65165 Hello,
while comparing the functional block diagram (Figure 20. of the TPS65165 datasheet of Feb 2017) with the reference design of the TPS65165EVM in slvu548 I noticed that in the datasheet…
Hello Andrea,
Do you need the operational amplifiers that are part of TPS65165 and the gate voltage shaping block? If not, I would recommend to have a look at TPS65100. You might use the VCOM buffer to generate your VCOM.
For the 11V 30mA, I would…
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
Siyu,
I think the toggle flip-flop in the block diagram on page one of the spec should have let you know that the max you will get with this device is 50% duty.
Go to page 43 and 44 of the attached and select a more suitable part.
Peter,
i am enclosing the Power Management Guide for 2011. The section you will be interested in starts on page 43 and actual devices listed on page 46, With the minimum information you have given me I would expect that you will want something like…
Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
Gary,
Most any of our power controllers with dual output capability will provide the control. See attached document starting at page 50 with the dual output controllers on page 53 and 54 and choose what features you want.
Regards,
John
